999783 ÷ 28 
The aim is to understand the frequency of 28 in 999783.

Going ahead to step 1:
If we divide 9 by 28, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 28

Advancing to step 2:
The number 28 fits into 99 3 times, leaving a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 84 from 99 to get 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 28

Moving on to step 3:
If we divide 159 by 28, we get 5 and a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 140 away from 159, we end up with 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 28

Step 4:
The number 28 fits into 197 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 357.0
If we take 196 away from 197, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 28

Let's proceed to step 5:
28 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 3570.0
Subtract 0 from 18 to get 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 28

Moving on to step 6:
28 can be fit into 183 6 times, resulting in a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 35706.0
Deduct 168 from 183 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 28 fits into 150 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 35706.5
Subtract 140 from 150 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 28, we get 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 35706.53
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
160 divided by 28 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 35706.535
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
28 goes into 200 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 35706.5357
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 35706.53571
If we take 28 away from 40, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
28 goes into 120 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 35706.535714
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
80 divided by 28 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 35706.5357142
Subtract 56 from 80 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
28 goes into 240 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 35706.53571428
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 35706.53571428 with a remaining 1.6e-08.
